Let’s Get Your Ingredients Ready

• 3 lbs Yukon Gold potatoes, sliced 1/8-inch thick
• 1 tbsp olive oil
• 1 yellow onion, thinly sliced
• 3 cloves garlic, minced
• 8 oz cremini mushrooms, sliced
• 4 oz shiitake mushrooms, stems removed & sliced
• 1 (10.5 oz) can condensed cream of mushroom soup
• 1 1/2 cups heavy cream
• 1 cup vegetable broth
• 1 tsp fresh thyme leaves, plus more for garnish
• 1/2 tsp smoked paprika
• Salt and black pepper to taste
• 2 cups shredded Gruyère cheese, divided
• 1/2 cup grated Parmesan cheese

Bringing This Recipe to Life (Step-by-Step)

1

Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish.

2

Heat the olive oil in a large skillet over medium heat. Add the onion and cook until soft, about 5 minutes.

3

Add the garlic and all the mushrooms. Cook until the mushrooms have released their liquid and are golden brown. This builds incredible flavor!

4

In a large bowl, whisk together the cream of mushroom soup, heavy cream, vegetable broth, thyme, smoked paprika, salt, and pepper.

5

Stir in 1 cup of the Gruyère cheese and all of the Parmesan into the creamy soup mixture.

6

Arrange half of the potato slices in the bottom of your prepared dish. It’s okay if they overlap.

7

Spread all of the cooked mushroom and onion mixture evenly over the first potato layer.

8

Top with the remaining potato slices, arranging them nicely.

9

Pour the entire savory sauce mixture over the top, making sure it seeps down into all the layers. Gently shake the dish to help it settle.

10

Cover the dish tightly with foil and bake for 50 minutes.

11

Carefully remove the foil. Sprinkle the remaining 1 cup of Gruyère cheese over the top.

12

Bake, uncovered, for another 20-25 minutes, until the top is gorgeously golden and bubbly, and the potatoes are tender.

13

Let it rest for 15 minutes before serving. This is crucial for the perfect slice!

Add a layer of fresh spinach with the mushrooms. It wilts down perfectly and adds a pop of color.

Swap the Gruyère for a sharp white cheddar. It gives a totally different, but equally amazing, cheesy kick.

For a hearty protein boost, mix in a can of drained, white beans or some cooked lentils with the mushroom layer. It makes it a full meal! For another hearty, protein-rich dinner idea with a smoky kick, don’t miss this 5-minute prep Chipotle Beef Casserole.

A Quick Q&A on This Recipe

Can I make this ahead of time?

Absolutely! I do this all the time for holidays. Assemble the whole dish, cover it, and keep it in the fridge for up to 24 hours before baking. You might need to add 5-10 extra minutes to the bake time since it’s cold.

What’s the best potato to use?

I swear by Yukon Golds. They have the perfect buttery flavor and creamy texture. Russets work too, but they can be a bit more starchy. Yukons are my golden ticket to perfection.

Is there a way to make it lighter?

For sure! You can use half-and-half instead of heavy cream. The sauce will be a little less rich, but still totally delicious. I’ve done it and loved it.

Wow! Look what we just made together. A masterpiece of creamy, earthy, cheesy goodness. This dish is pure comfort food magic.

It’s the star of the dinner table. The ultimate hearty side that steals the show. I am so proud of you for making it!
